Wherein, the water inlet and the jet hole 2 of the nozzle body 1 are usually disposed at two opposite sides of the nozzle body 1, and the size of the water inlet is often much larger than that of the jet hole 2.

In this embodiment, the water inlet of the nozzle body 1 may be communicated with the inlet end of the spiral channel, and certainly, the inlet end of the spiral channel may also be directly used as the water inlet of the nozzle body 1, which means that the axial end surface of the spiral channel coincides with the side surface of the nozzle body 1 provided with the water inlet; the jet hole 2 of the nozzle body 1 is communicated with the outlet end of the spiral channel. It can be seen that after the liquid medium such as water enters the nozzle body 1 from the inlet, the liquid medium accelerates along the spiral channel and finally is ejected from the ejection holes 2. In this process, the liquid medium is accelerated and pressurized at the spiral passage and the injection holes 2, thereby being atomized and injected at the injection holes 2.

This atomizer sets up spiral channel in the finite space of shower nozzle body 1, and spiral channel can guide liquid medium such as water to flow smoothly, naturally from the water inlet of shower nozzle body 1 to the jet orifice 2 of shower nozzle body 1 on the one hand, and on the other hand can prolong the flow path of aforementioned liquid medium as far as possible to make liquid medium obtain bigger pressure and velocity of flow in spiral channel, improve atomization effect. Therefore, the atomizing nozzle continuously supplies water to the water inlet of the nozzle body 1 on the premise of not increasing the resistance of the jet hole 2 and the water supply pressure, so that the water in the spiral channel is secondarily pressurized in the spiral channel, the sprayed water mist particles are thinner and smaller, and the atomizing effect of spraying is greatly improved.
